BLOOD BORON LEVELS IN HUMAN INFANTS

[摘要] The average blood boron concentration in 34 patients exposed only to dietary boron was 0.25 [mu]g/ml. The highest level reached in this group was 1.25 [mu]g/ml. 37 patients exposed to boron-containing medications as well as dietary boron showed an average blood boron concentration of 0.20 [mu]g/ml and a high of 1.25 [mu]g/ml. These are not significantly different from the levels in the first group of patients described above. Two children who accidentally received a boric acid solution orally showed blood boric acid levels of 7.89 mg % and 7.44 mg % respectively. Neither exhibited any signs of boric acid toxicity despite the fact that these levels are above those previously reported as fatal.
